2nd Camera view what 1st Camera rendered (Occlussion Culling)

Hello everyone,
I’m new to the Unreal community and am currently working on a project where I want to demonstrate culling techniques. I’m using Unreal Engine 5.7.4.

I’m currently looking for a solution to my occlusion culling problem:
I have a player camera that applies occlusion culling as intended. To check this, I’m currently using “FreezeRendering”.

Now, however, I’d like to add a second camera that looks down on the player from above, but only renders the same objects that the first camera renders so I can see the rendering effect live. I want to add the 2nd camera view into a little popup or anything like that.
Unfortunately, I haven’t found a solution for this yet. Is this even possible?

Thanks for your advice
